“I think he thinks he’s got three mommies,” the Rogue star joked on the TODAY show Thursday. “He’s got a 13-year-old, a 9-year-old and a … 27-year-old.”

Newton is actually 41, but she did get the ages of daughters Nico and Ripley right. The proud mama had all three children with a midwife at home, noting on TODAY that her boy was born “on the bathroom floor.”

The couple, who wed in 1998, are already parents to daughters Nico, 9, and Ripley, 13. The girls were at the labor of their little brother, who weighed in at 8 lbs., Newton’s rep tells PEOPLE.Read More

The moms-to-be — who are at very different stages in their pregnancies — each opted for looks that really flattered their growing curves. While attending the Saturday premiere of her new movie Labor Day, Winslet wore a navy empire waist silk gown by Jenny Packham and paired it with Roger Vivier‘s luxe Maxi Boite de Nuit clutch.

Newton, on the other hand, donned Stella McCartney‘s Wave Colorblock Sheath ($795), which perfectly accented her beginner belly. And for accessories, the actress went for the designer head-to-toe by pairing her dress with a Stella McCartney gold and black clutch and ankle-strap platform heels.
